As the two pilots came around for a second pass, anti-aircraft fire opened up from below, and caught Lynch's P-38 in the right engine, and caused it to burst into flames. Bong's P-38 was also damaged in one engine and holed.

On the ground at Aitape, the anti-aircraft fire was from the Japanese Navy 90th Garrison Unit under the command of Warrant Officer Hideo Ezawa emplacted with two 7.7mm machine guns and three 13mm machine guns fired on the P-38s. They claimed Lynch's P-38 was hit and "the entire nose section [was] blown off and starboard engine on fire."

After being hit, Bong radioed him to bail out. Lynch climbed to 25,000' but was unable to bail out until too close to the ground. His parachute barely open before he hit the ground. From above, Bong witnessed him hit the jungle, and his aircraft crash one mile south-southwest of Aitape into a mangrove swamp. When Lynch failed to return, he was officially declared Missing In Action (MIA).

MemorialsLynch was officially declared dead the day of the mission. He is memorialized on the tablets of the missing at Manila American Cemetery. He also has a memorial marker at Calvary Cemetery in North Catasauqua, PA.

"“On 9 March 1944, the great Tommy Lynch died. He and Dick Bong had been successful in the Tadji area, so they set off to sweep the location again. The 78 Sentai sent two Tonys to intercept but did not make contact. The P-38's strafed three luggers offshore and sank Yashima Maru, with the captain and one other man killed and three wounded. The P-38s turned for another pass at twenty feet height.
Unknown to Bong and Lynch, a forty-five-man detachment pf the Japanese navy’s 90 Garrison Unit, commanded by Warrant Officer Hideo Ezawa, was onshore, equipped with two light 7.7 mm and three heavy 13 mm machine guns, with 7,000 rounds of ammunition. Some of the unit personnel had only just arrived in New Guinea from Formosa, arrived at Palau on 20 February, and went on to Tadji. They fired at Lynch and Bong, and Bong later reported that on Lynch’s P-38, “the entire nose section [was] blown off and starboard engine on fire.” Lynch pulled up to twenty-five hundred feet to bail out, but did not get out until the P-38 was down to one hundred feet; the fighter exploded, and simultaneously, Lynch’s parachute streamed but did not have time to open. Leading Seaman Amano was credited with the victory, but the Japanese merely claimed a P-38, never knowing they had shot down one of the greatest fighter leaders in the SWPA. Tommy Lynch joined the long list of superior pilots brought down by ground fire.
The Japanese navy gunners shot well and almost downed two leading aces, because Bong had to feather one engine to return to base, and his crew chief at Nadzab found eighty-seven bullet holes in the P-38. The loss of Lynch was the only time the ground crew saw Dick Bong show any signs of nervousness. Bong did say that Lynch’s death was the hardest blow he suffered in the war.” AcePilots.com - Thomas Lynch, C.O. 39th FSAerial Victory Credits - Thomas J. Lynch
